The Coromuel Wind — Why Every Cabo Captain Departs at Sunrise
A 350-year-old local wind, a British pirate, and the afternoon breeze that shapes every fishing day in the Sea of Cortez. Here's what anglers need to know.
What is the Coromuel Wind?
The Coromuel is a warm, thermal-driven wind unique to the southern Sea of Cortez — particularly around La Paz and Los Cabos. It typically blows from the southwest in the afternoon and evening (3-8 PM), cooling off summer heat and stirring the sea surface. Speeds range from 10-25 knots. For anglers, the Coromuel is the main reason experienced Cabo captains depart at 6:10 AM sharp — so you're back at the dock before the wind stacks chop on the surface.
Coromuel at a Glance
How a British Pirate Named a Baja Wind
The name "Coromuel" comes from Thomas Cromwell — an English pirate (or privateer, depending on who you ask) who raided Spanish galleons in the Sea of Cortez in the 17th century. Spanish sailors in the Baja peninsula observed that Cromwell consistently timed his afternoon attacks to coincide with the favorable southwest wind.
Over decades, the Spanish locals pronounced his name "Coromuel" — a phonetic corruption of Cromwell — and eventually the name stuck not for the pirate himself, but for the wind he used so skillfully. Today, Baja Californianos still call this afternoon breeze the Viento Coromuel, and every local fisherman plans their day around it.
It's one of the few winds in the world named after a person — and the only one named after a pirate who never knew he'd become part of Mexican meteorological folklore.
The Coromuel Daily Pattern — Hour by Hour
The wind follows a predictable rhythm. Here's how it builds throughout a typical summer day in Los Cabos:
⏰ Wind Intensity Through the Day
💡 Captain's observation: The sweet spot for calm fishing is 6:10 AM to 1:00 PM. After 2 PM, the Coromuel starts stacking chop, and by 4 PM most boats return to harbor. This is why our 6-hour trips end before 1 PM — we give you the best 6 hours, not random hours.
Why Every Cabo Captain Leaves at 6:10 AM
Completely calm waters. Zero wind. The Coromuel is still hours from starting.
Sunrise run offshore — glass calm seas, perfect for tuna spotting and trolling setups.
The fish are actively feeding, the wind is zero-to-light, and the boat ride is smooth. Peak comfort + peak action.
Light wind starting to build — still manageable. Return run to harbor while seas are moderate.
Trip is over, fish are on ice, and the Coromuel is picking up. Smart anglers are already ordering tacos.
Rough seas offshore. Afternoon trips are usually less comfortable — this is why we don't run them in summer.
Where the Coromuel Hits Hardest
The Coromuel's intensity varies dramatically by location along the Sea of Cortez. Here's what you need to know:

💡 Local insight: Cabo San Lucas sits on the Pacific side, so it gets less Coromuel influence but more open-ocean swell. San José del Cabo is in the sweet spot — protected enough from heavy Coromuel, close enough to Gordo Banks for offshore runs. This is one of the reasons anglers pick Puerto Los Cabos over Marina Cabo San Lucas for serious fishing.
Coromuel vs Other Baja Winds
The Coromuel isn't the only wind in Baja. Here's how the 3 main seasonal winds compare — and which ones affect your fishing trip:
Coromuel
Afternoon · Summer · SWThe warm afternoon wind from the southwest. Predictable, local to Baja Sur, and the reason captains depart early.
- SeasonMay-October
- Time3-8 PM
- Speed10-25 knots
- Fishing impactModerate
El Norte
Winter · Morning · NThe cold northern wind blowing down the Sea of Cortez in winter months. Can create big chop and affect trip comfort.
- SeasonDec-Feb
- TimeOften all day
- Speed15-35 knots
- Fishing impactHigh
Chubasco
Late summer · Storm · VariableShort, intense tropical storms or squalls — often preceded by a hurricane or low-pressure system in the Pacific.
- SeasonAug-Oct
- TimeUnpredictable
- Speed30-60+ knots
- Fishing impactSevere · cancel trip
How to Prepare for the Coromuel as an Angler
- Book early-morning trips. 6:10 AM departures get you on the water before the wind builds.
- Choose your boat wisely. Larger boats (33ft-38ft) handle Coromuel chop better than pangas. If you book an afternoon trip in peak season, go bigger.
- Bring layers. Coromuel drops temperatures 5-10°F in the afternoon — a light windbreaker is useful even in summer.
- Avoid afternoon trips in July-September. That's peak Coromuel season. Morning trips always win.
- Trust your captain's call. If we say "let's head back early," it's because the Coromuel is building faster than forecast.
- Hydrate extra. The wind dries you out faster than you realize. Bring 2L of water minimum.

Frequently Asked Questions
What exactly is the Coromuel wind?
The Coromuel is a thermal-driven, warm afternoon wind that blows from the southwest across the southern Sea of Cortez. It's caused by daily temperature differences between the Pacific Ocean (cooler) and the Baja California landmass (hotter). As hot air rises over Baja during the day, cooler Pacific air rushes in to replace it — creating the Coromuel breeze from the SW.
Why is it called Coromuel?
The name comes from Thomas Cromwell, a 17th-century English pirate who raided Spanish galleons in the Sea of Cortez. Spanish locals noticed he timed his attacks with the afternoon wind, and over time "Cromwell" was pronounced "Coromuel" in Mexican Spanish. The pirate is gone, but the name stuck.
What time does the Coromuel usually start?
The Coromuel typically starts building around 12-1 PM, peaks from 3-6 PM, and eases after 9 PM. Early mornings (before 11 AM) are almost always calm — which is why Cabo fishing departures are scheduled for 6:10 AM sharp.
Does the Coromuel blow every day?
From May through October, yes — on most days. It's a seasonal pattern tied to summer heat. Winter months (November-April) have occasional Coromuel activity but also include El Norte (northern wind) which is a different pattern altogether.
Does the Coromuel affect fishing in Cabo San Lucas?
Much less than in San José del Cabo or La Paz. Cabo San Lucas sits on the Pacific side, so the Coromuel weakens before reaching it. However, Cabo SL gets more open-ocean swell from the Pacific. The trade-off is why serious anglers often pick Puerto Los Cabos — it balances wind protection with quick access to Gordo Banks.
Can I fish in the afternoon during Coromuel season?
Yes, but with caveats. Afternoon trips in summer are rougher, and some smaller boats don't run them. If you must fish afternoon, book a larger boat (33ft+) and expect chop. Our Afternoon Fishing trips are typically available in calmer months (November-April) when the Coromuel rests.
Is the Coromuel dangerous?
For experienced captains on properly-equipped boats, no — it's part of normal Baja weather. For inexperienced operators or undersized boats, it can become uncomfortable or risky. When the Coromuel exceeds 25 knots sustained, some captains will return to harbor early. Port closures are rare but possible if combined with a hurricane or tropical storm system.
Does the Coromuel affect fish behavior?
Yes, slightly. Strong surface chop can scatter bait pods and make trolling less efficient. Many fish move deeper during peak wind hours. This is another reason to fish in the morning — fish are more active near the surface when water is flat and calm.
What's the difference between Coromuel and El Norte?
Coromuel is a warm summer wind from the southwest (peaks in afternoon). El Norte is a cold winter wind from the north (can blow all day). They happen in different seasons and from opposite directions. See our Winds Comparison above for the full breakdown.
Can you predict the Coromuel day-to-day?
Roughly, yes. Local captains use Windguru and NOAA forecasts, but 15+ years of local experience helps more than any app. We check the weather the night before every trip and contact you if conditions change. If the forecast shows Coromuel exceeding 25 knots, we often recommend rescheduling.
